RS HiVegâ„¢ Medium Base 500G

RS HiVegâ„¢ Medium Base is used for selective isolation, cultivation and presumptive identification of Aeromonas hydrophila from clinical and non-clinical samples.It is used for selective isolation and presumptive identification of Aeromonas hydrophila and other gram-negative bacteria based on their ability to decarboxylate lysine and ornithine, maltose fermentation and H2S production. Yeast extract acts as a source of nutrients. Sodium thiosulphate, L-cysteine hydrochloride and ferric ammonium citrate are the indicators of H2S production. Maltose is fermentable carbohydrate source. Bromothymol blue is the pH indicator. Sodium deoxycholate and novobiocin inhibit gram-positive bacteria and Vibrio species. Aeromonas hydrophila show yellow coloured colonies due to maltose fermentation, Lysine and ornithine decarboxylation negative and do not produce H2S. This medium is prepared by replacing animal peptones with vegetable defined peptones to avoid BSE/TSE/GMO risk.
